This book deals with modelling and simulation techniques and its application in the field of fibrous materials. The different modelling and simulation techniques covered in this book include finite element analysis, computational fluid dynamics, artificial neural network, fuzzy logic, empirical and statistical modelling. In addition, this book is a good reference volume for undergraduate to graduate level courses covering the background, current trend and applications of modelling in fibrous materials. This book is also a good source of information for a number of inter-disciplinary departments like mathematics, materials science, mechanical, chemical and textile engineering, and computer science.
